How does a vacuum emulsifier work?

Introduction

Vacuum emulsifiers are crucial to the production processes in various industries, including cosmetics, pharmaceuticals, and food processing. Understanding the operational mechanisms and efficiencies of these machines allows companies to optimize their production lines.

Mechanism of a Vacuum Emulsifier

The core function of a vacuum emulsifier lies in its ability to mix components under reduced pressure. This environment minimizes the presence of air, which can adversely affect the quality of the emulsion. Here’s how a vacuum emulsifier works:

• The emulsifier consists of a vacuum system, mixing chamber, and high-shear homogenizer.
• Materials are loaded into the mixing chamber, and air is evacuated to achieve a vacuum level typically between -0.09 to -0.097 MPa.
• The homogenizer creates a shear force of up to 30,000 rpm, enabling the mixing of immiscible liquids into a stable emulsion.
• Temperature control systems maintain the process temperatures between 20 to 80°C, depending on the materials being processed.

Process Parameters and Efficiency

Key parameters influencing the efficiency of a vacuum emulsifier include:

• Vacuum Pressure: Essential for removing air from the mixture, leading to higher purity levels in the final product.
• Shear Rate: A direct influence on particle size, typically targeted to achieve a droplet size of less than 2 micrometers for most cosmetic creams.
• Mixing Time: Ranges from 15 to 60 minutes, with variations depending on material viscosity and desired emulsion quality.

Efficiency is measured by mixing homogeneity, droplet size distribution, and energy consumption, with well-tuned systems achieving energy efficiency ratios of about 10 kWh per ton of emulsion.
